My VZ iPad 2 is having connectivity issues. Essentially, I'll have the iPad connected to 3G, and it won't connect to my VZ account. I'll launch Safari, and the iPad refuses to load because "There is no data remaining on your current plan". However, I sign in, and my account says that I have used NONE of the data I paid for, which is true. I then exit the account prompt, and the iPad continues to provide zero data. I've changed credit cards in my account, updated the software, restarted, etc, but nothing fixes the issue. Any suggestions?
